“It’s flat & motionless Folks! From the Pilot’s basic study guide; please read 1.1.2 & let that sink in! Every Pilot was taught this, but some still don’t get it, (I didn’t at first) & some just stay asleep & yes it does say ‘assumed’ but when does the theory become a spinning reality? Where is the next part B manual to apply Coriolis & curvature nonsense to any flight? Never…because it is a flat & stationary Earth we live & fly on. All flight planning & aerial navigation is based always on a flat motionless plane! Curvature or spin is never accounted for EVER 😱☯️😴”
Flat nonrotating earth
“The nonlinear equations of motion used are six-degree-of-freedom equations
sith stationary atmosphere and flat, nonrotating earth”
Determination of Angles of Attack and Sideslip from Radar Data and a Roll Stabilized Platform
NASA – March 1972 page 2:
“The method is limited, however, to application where a flat, nonrotating earth”
An Aircraft Model for the AIAA Controls Design Challenge
NASA – 1991 – page 11:
“The nonlinear equations of motion used in this model are general six-degree-of-freedom equations representing the flight dynamics of a rigid aircraft flying in a stationary atmosphere over a flat non-rotating earth”
Investigation of Aircraft Landing in Variable Wind Fields
NASA 1973 – page14 pdf or 6 on actual report:
a) The earth is flat and non-rotating.
A Mathematical Model of the CH-53 Helicopter
NASA – page 17:
“The helicopter equations of motion are given in body axes with rerpect to
a flat, nonrotating Earth.”
Georgia Tech April 1965
Prepared for NASA
A model frequently used is that of a flat, nonrotating earth.
These equations assume a rigid vehicle and a flat, nonrotating Earth.
Flight Testing a VSTOL Aircraft
NASA 1988 – page 9 pdf or 4-5 on actual doc:
“For aircraft problems, the state and measurement models together represent the kinematics of a rigid body for describing motion over a flat, nonrotating Earth…”
Time to Climb
“In our minimum time-to-climb problem, the aircraft is modeled as a point mass and the flight trajectory is strictly
confined in a vertical plane on a non-rotating, flat earth.
